What I am looking for is a good projectile for doing demos. Golf balls are the obvious choice, but they get to be expensive. Stones are cheap, but hard to see in flight.
  What would be perfect is a cheap, visible projectile that is biodegradable, or environmentally friendly. Any ideas?? ???

Flour glandes maybe?

Spraypaint the stones bright orange, and people won't have a hard time seeing them. Cheapest way out I think

raw eggs

  I'd suggest frozen eggs or hardboiled eggs, eggs are pretty cheap around here, under a dollar a dozen. 

well i bet the biodegradable ones break down faster, seeing as how plastics don't break down naturally like other materials

Hey.....if they are edible then all bets are off!

Open up Pedro, it's only 40 meters!  Ok then, no water for you today unless you can catch it from my sling!

I’ve thrown oranges. Don’t worry, I don’t throw ones that are edible or will likely become edible if allowed to continue to grow.  Anyways I threw an orange from my house over a parking lot towards an intersection late at night (no cars were present). The orange disappeared into the darkness and then I heard a distant WAP!  I had no idea what I hit.  I didn’t think I threw hard enough to hit the buildings on the other side of intersection.  The next morning I looked for the orange. I couldn’t find it anywhere. Then I looked up and saw remnants of the orange “ground” into a wooden telephone pole about 8 feet up. I paced the distance and estimate it was about 98 yards.
